SLIVER-CLEANER FLIER.

Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed March 1, 1917. Serial No. 151,786.

To all whom it may concern:

Be it known that I, EDWARD F. BENOIT, a citizen of the United States, and resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Sliver-Cleaner Fliers, of which the following is a specification.

This invention relates to fliers used in conjunction with slubbing and other like or similar machines, in which roving is drawn and twisted, and the invention, more specifically, is an improvement over Letters Patent No. 1,222,810, upon sliver cleaners for fliers, issued to me on or about April 17 1917.

The dominant feature of my invention is to provide a novel means, whereby, various matter which may be in or adhering to the sliver will be removed therefrom, previous to the coiling of the same about the bobbin, consequently, eliminating much loss and trouble in the subsequent spinning operation.

It is also an object of my invention, and one of equal importance, to provide a sliver cleaner or scraper for fliers through which roving varying in size may be passed and efficiently cleaned thereby.

A further object of my invention is to provide a sliver scraper which may be readily threaded without liability of breaking or tearing the roving in a minimum space of time.

Among other aims and objects of my invention may be recited, the provision of a sliver scraper of the character mentioned with a view to compactness, and in which the number of parts are few, the construction simple, the cost of production small, and efficiency and operation high.

In order that the invention and the manner of its application may be readily understood by those skilled in the art, I have in the accompanying illustrative drawings and the detailed following description based thereon set forth the preferred embodiments, of the invention.

In the drawings:

Figure 1 is a side elevation of a flier with my improved sliver cleaner applied thereto;

Fig. 2 is a fragmental top plan of the flier showing the arrangement of the scraper thereon;

Fig. 3 is a similar view of yet another slightly modified form;

the numeral 1 straddles a bobbin 2 about which the twisted roving is wound, the flier being applied to the spindle .for said bobbin in the usual well known manner and the bobbin is of. the ordinary well known construction. One of the depending arms 3 of the flier 1 is formed hollow or tubular and receives therethrough the sliver designated by the numeral l, the sliver being passed through the same and then about a suitable presser arm, not shown, whereupon said sliver is wound about the bobbin 2 in an efficient manner. The nose 5 at the upper portion of the flier 1 is integral therewith and has provided therein an axial opening 6, through which the sliver 1 passes, previ one to its introduction into the tubular arm 3. A flier slot 6 is formed in one side of the nose 5 and extends through the top thereof, whereby the sliver Al may be readily threaded in the axial opening 6 by merely passing the same into engagement therewith and working it downward into the said axial opening.

With a view toward providing eificient cleaning or scraping means whereby various matter as within or adhering to the sliver or roving will be removed therefrom, I arrange at the upper end of the tubular arm 3, a scraping element indicated by the numeral 7 which scraping element comprises the base 8 having a diagonally disposed plate 9 extending therefrom, in which plate a diagonally arranged slot or way 10 is formed, the lower portion of which is enlarged as at 11, while one side of the upper portion thereof is beveled as at 12, to permit the ready insertion of the sliver or roving thereinto and threading the same. As will be noted, the forward end of the base 8 is con caved as at 13, whereby, the same may be snugly received about a portion of the nose 5 and then secured in position to the flier 1 by means of suitable fastening devices which are passed through spaced apart apertures 14 as formed in the said base. By so arranging the scraper 7 upon the flier, it

will be appreciated, that previous to the passing of the sliver or roving into the tubular arm 3, such foreign matter as may be within or adhering to the same will be thoroughly removed therefrom and as a consequence, much less and trouble as will be invariably encountered in subsequent spinning operations will be eliminated.

In the Fig. 3 I have disclosed another slightly modified form of sliver scraper, the scraping plate per 86 being identical in shape and arrangement to that as shown by the Fig. 2, but being provided with a plurality of sliver receiving slots or ways 15 and 16, respectively, which slots extend diagonally of the scraping plate and are enlarged at their lower extremities. To permit ready threading or insertion of the sliver into the said ways, certain of the upper portions thereof are beveled as at 17 Thus, insertion of the sliver into the said ways 15 and 16'may be instantly made with out liability of breaking or tearing the same, It is to be noted, that the slots 15 and 16 together with their respective enlarged lower extremities are of: different size, thereby, providing for means which will receive and efiiciently clean or scrape slivers, or rovings of varying size. By providing a plurality of sliver receiving ways within the scraper plate, it will be readily appreciated, that the attachment may be used continuously, without the necessity of removing the same to replace a scraper provided with means for receiving a different size of sliver or roving.

In Fig. 4, there is shown yet another modified form of my improved scraper, a plurality of different size sliver receiving slots 18 and 19 being formed therein, which slots have their side portions formed straight or continuous. Slivers or rovings of different size may be passed through the slots 18 and 19, by merely rethreading the same, that is, rearranging the slivers within the proper receiving slots 18 or 19.

In the Fig. 5 I have shown a slightly modified form of flier nose, designating the same by the numeral 20, the said nose having formed therein a plurality of spaced apart vertically disposed sliver ways 21 and 22, the latter, as will be noted, being of a width slightly less than the former in order that slivers varying in size may be passed through the nose 20 and thoroughly freed of such foreign matter as adhering thereto. It will be understood, that the nose 20 will not only serve as a means for directing the sliver into engagement with the scraping element, but also, will remove the particles of foreign matter as carried thereby, previous to its passage though the said scraping elements.

Still further embodiments of the invention than those herein especially defined may be resorted to as conditions or prefer ence may dictate, as may be in keeping with the hereto appended claim.

1' claim:

The combination with a flier having one of its depending arms formed hollow and terminating in a shoulder at its upper end, of a scraper plate fitting against the shoulder and bent to provide an attaching flange, the scraper plate being provided with a plurality of slots leading from the upper edge and communicating with roving receiving openings varying in size and each of greater diameter than the width of the slot communicating therewith at the junction of the slot and opening, the slots being widened at their outer ends.

In testimony whereof, I afiix my signature hereto.

EDWARD F. BENOIT.
